Be it known that I, Gnouon K. BRAYMEN, a citizen of the United States, residing at East Venom, in the county of La Salle and State of Illinois, have invented new and usefullmprovemcnts in Combination Gripper, Perforating, and Scoring Attachments for Printing Presses, of which the following is a'full, clear, concise, and exact description, reference being had to the accompanying drawing, forming'a part of this specifica- .tion.

This invention relates to a combination gripper and perforating or scoringattacl'land more particucharacter adapted cross-perforaar accomplished 111 the press at the same time that the printing is being performed. Devices adapted and upright scoring are old in the art, but when these de vices are to be utilized on blanks which it is desired to cross-score or perforate, it is necessary to run the blanks through the press a second time for the cross-scoring, which operation is known in the trade as a double run.

One of the objects ofthis invention, there fore, resides in the production of an improved device in which the printing and upright and cross-scoring and the like can be performed in one operation, so as to eliminate the so-called double run The invention comprises an improvement on the combination gripper-and scoring de vice illustrated and described in the United States Patent to H. issued July 2nd, 1918, and comprises additions and modifications to the apparatus described in said patent [whereby the desired upright and cross-scoring can beperformed in one operation. I

Another object of the invention comprises the production of an iniproveddevice of this character which produces upright and cross-scoring, which meet at a substantial larly to a device of this,

. right angle corner and in which the crossscoring does not extend beyond thel-ine of the upright scoring, an evil which is preva- Cole No. 1270788,

combination gripp extension consists of the mounting} element orbase cross-scoring attachment can be adjusted to,

any desired position with respect to the upright score.

A still further object comprises the production of an apparatus capable of carrying a plurality of cross-scores, each of which is adjustable with respect to the upright score and with respectto one another.

Other objects of the invention will become apparent from the following description, the accompanying drawings, and the appended claims.

For the purposes of description, the pre ferred embodiment oft-he invention is illustrated in the accompanying drawings, in which- Fig. l is a view in front elevation of the upright combination gripper and perforator fitted with two cross-perforators;

Fig. 2 is a view of a portion of the crossgripper, partly in section, taken on the plane indicated by the line 22 of Fig. 1, looking in the direction of the arrows;

Fig. 4 is a side elevation, partly in section, of the combination vertical gripper and scoring attachment Figs. 5, 6 and 7 are side views of interchangeable blades for use in connection with the scoring or perforating attachments;

Fig. 8 is avertic'al section of the crossscoring and perforating attachment taken on the plane represented. by line 88 of Fig.2, looking in the direction of the arrows; and r v f Fig. 9 is ablank which illustrates the character of scoring which may be obtained, together with the printing, in one operation of the'piess. I

Referring to the drawings, the upright and scoring attachment v10 which carries at either endthe springs 11' and 12 respectively, which springs cooperate with the blade-carrier 13 whereby either end thereof.

the blade 1 1 is normally held in position in the slot 15 of the base 10, so that the cutting edge of the blade is entirely enclosed within said slot. The blade-carrier 13 is equipped at either end with a countersunk hole such.

as 16, said hole carrying a screw 17 which is threaded into the base 10. The head of the screw 17 is loosely fitted in the countersunk portion of the hole 16, the head of the screw serving to limit the upward movement of the blade-carrier 13 under the action of the springs 11 and 12. Thus, when. the blade-carrier 13 is moved to the extreme position under the influence of the springs 11 and 12, in which position the head of the screw 17 contacts with the lower portion of the countersunk part of the hole 16, the blade 14, positioned in the blade-carrier 13, will be completely enclosed within the slot 15 of the mounting-base 10.

The blade 14 may be secured to the blade carrier by any suitable means, but, in the preferred construction illustrated in the drawings, this is accomplished. by a screw such as 18 fitted into the blade-carrier at The screw 13 is flat headed and the head of the screw contacts with slots such as 19 cut in either end of the blade 14, the head of the screw and the slot 19 cooperating to securely hold the blade 14: in a slot 20 cut in the blade-carrier to receive the top portion of the blade.

The upper face 21 of the blade-carrier is milled out at one edge thereof for the purpose of obtaining a flat face portion 22 below the upper face 21 of the remaining portion of the blade-carrier 13. The purpose and function of this depressed face 22 will be explained hereinafter.

Adjacent the edge of the blade-carrier 13, which is fitted with the depressed face 22, is a groove or slot 23 which extends for substantially the entire length of the blade.- carrier and which is fitted at the upper end with a cut away portion 2 1. This groove or slot 23, together with the depressed face 22 on the top of the blade-carrier, functions to connect the end of the cross-perforator with the upright gripper or perforator. This interconnection between the cross-perforator and the upright perforator is clearly illustrated in Fig. 2.

As illustrated in Fig. 2, the end of the blade-carrier 25 of the cross-perforator is formed to produce a hook portion 26, the forwardly upwardly extending part 27 of said hoot: portion snugly fitting in the groove 23 of the upright blade-carrier. The top face of the crossblade-carrier 25 is cut away at the hook end to receive. a flat spring 27, which projects over the end of the crossblade-carrier and onto the depressed portion 22 of the upright blade-carrier. The spring 27 is secured to the cross-blade-carrier by any means, preferably by rivets such as 28. As illustrated in Fig. 1, these rivets secure the spring 27 to the cross-blade-carrier 25 at substantially the extreme inner end so as to give the projecting end of the spring 27 the desired amount of resilie cc, whereby said spring will function to tightly hold the hook portion 26 of the cross-perforating blade-carrier in the gro re 23 of the upright perforating blade-carrier. The cross-blade-carrier is fitted with a slot 29 to receive the cross-perforating blade 30, the blade being secured to the carrier 25 by screws such as 31 in a manner identical to that described in connection with the blade securing means for the upright perforator.

The vertical movement of the cross-bladecarrier, whereby the cutting edge of the blade 30 is confined within slot 32 of amounting base 33 of the cross-perforating mechanism, is securedby springs such as 3 1 and the spring 35, together with the limiting screws such as 36. The limiting screws 36 are secured in the mounting base and fitted in countersunk holes in the blade-carrier 25 in a manner identical to that described for the same mechanism in connection vith the upright perforator. The spring 35 secured to one end of the base 33 (see 3), and adapted to maintain one end of the blade-carrier 25 in its normally raised position is secured to the base 33 in any manner, preferably by rivets. The springs 3 1, which function to maintain the other end of the cross-blade-carrier 25 in its normally raised position, are fitted in slots 36 positioned in the side of the blade-carrier 25 and are secured in this position preferably by means of rivets. These springs 34 have a forwardly and downwardly extending portion 37 which contacts with the base portion 33, the springs normally beingin compression so as to maintain this end of the blade-carrier 25 in the extreme raised position against the heads of the screws 36. A spring such as 3% is secured. to the cross blade-carrier in the same position on either side of the blade 30.

The base portion 33 carries a countersunk surface 38 over which is positioned a plate 39 which is fitted with a like countersunk surface 10, the two countz-nrsunlr surfaces combining to form a slot adapted to receive the arm 41 of a gripper 12. The slot formed by the countersunk portions and d0 of the base 33 and plate 39 respectively is designed so that one edge thereof is slightly tapered to receive the tapered side as of the gripper 12. The gripper and the base 10 are each equipped with perforations such as 44 by means of which they are adapted to be mounted on suitable mechanism of the press by any means well known to those skilled in the art.

The base plate 33 ofthe cross-perforating mechanism is slotted for substantially the art.

entire length of the blade, and as illustrated in Fig. 8, the one end of this base plate is fitted with a pin 46 which serves to hold the two arms of this base plate in alignment, the cross-perforatingblade 30 being suitably slotted so that the blade will readily ride over the pin 46.

Figs. 5, 6 and 7 show blades which can be interchangeably"connected to the bladecarriers, the blade 14 of Fig. 6 showing a perforating blade in which the perforations extend for the entire length of the blade.

Fig. 5 shows a blade47 which has perforations for only a portion of its length, and Fig. 7 shows a blade 48 used for either cutting or scoring. i

In this specification. Whenever any of the terms cutting, scoring or perforating. are used to describe the means utilized for making the impression upon the paper upon which the printing is being performed, it is to be understoodthat these terms are used synonymously; that is, that the blades can be readily interchanged, and that the apparatus is equally well adapted to perform either perforating, scoring or cutting operations.

It will be understood thatin the operation of the press to which the apparatus herein described is to be applied, that the successive actions of the platen of the press serve to depress the upright and crossblade-carriers and force'the operating or cutting edges of the blades into or through thepaper or cardboard on which the printing and scoring or cutting operation is being perform d. i

It will likewise be understood that the blades can be readily interchanged by removing screws such as18 whereby the ap paratus can be adapted to suit the prospective work which it may be desired to accomplish.

In assembling the apparatus on the press the perforations 44 inthe base-l0 of the combination gripper and perforating attachment and inthe gripper 42 are secured to suitable means associated with the press ina manner well known to those skilled inthe When the gripper 42 and the combination gripper and perforating attachment have been thus secured to the press,'the arm'41 of the gripper 42 is pushed through the slot formed bythe' countersunk portions 38 and 48 in thecross-perforator bar.i The cross-perforator-bar is thenslid downon the arm 411 until the other'endoifthe cross gripper-bar reaches the opening 24 inthe upright combination gripper and perforator. When the other end of the crossperforator-bar is opposite this opening 24, the end of the cross-perforator-bar is inserted through said-opening 24 into the groove-23, and the cross-perforatorgbar is then pushed down on the arm 41 of the gripper and on the upright combination gripper and perforator. In this further movement the hookportion 26 of the crossperfora-tor-bar will ride in the groove 23 of the upright gripper and the spring 27 will solidly hold this end of the crossgripper-bar in its position and connection with the upright gripper. The end of the spring 27 will rest in the depressed face 22 whereby the top face of the cross-perforator and the top face of the upright perforator will all rest in substantially the same plane and represent a flush surface. The cross-grip-per-bar is now pushed down on'the gripper 42 and the combination gripper and upright perforator until the desired location has been reached. hen this position is attained, the cross-'perforator is positively positioned by means of screws such as 48 which serve to draw the plate 39 into close contact with the mounting base 33 of the cross-perforator whereby the upright arm 41 of the grip-per 42 will be rigidly clamped in the countersunk portions 38 and 43 which form the slot in which this upright arm 41 is positioned. This clamping action between the plate 39 and the mounting bar 33 serves to positively position the cross-perforator and prevents any movement thereof when it is acted upon by the platen of the press in the act of perforation. If a plurality of crossperforators are desired, these are secured to the gripper 42 and to the combination gripper and upright perforator in a manner identical to that which has just been described. These additional cross-perforators are positively positioned in the desired place by the same clamping action, and, consequently it will be evident that with an apparatus constructed in accordance with the teachings of this invention any number of cross-perforators may be used which may be adjusted and positioned as desired, so as to obtain any character of cross perforation.

Fig. 9 illustrates one character of blank which may be obtain d with the combination upright and cross-perforating app-aratus constructed in accordance with the teachings of this invention. It will be observed that in thisblank the upright perforation 50 is met by the two cross-perforations 51 and 52 at substantially right angles at 53 and" 54"respectively, and that the cross-perforators do' not extend over into the stubs 55; A sharp right angular relationship betwe n the upright and cross-perforators such as illustrated at 53 and 54 on the blank are obtained with this apparatus because the upright blade 14 meets the cross-blade 30 at substantially right angles and in substantially close contact, as clearly understoodin Fig. 2.

It will now be evident that with the apparatus described in this application it is possible to obtain printing and simultaneous upright and cross-perforation for each operation of the platen oi the press, and that the perforating apparatus can be adjusted so that any desired number of cross-periorations can be obtained with the upright perforation. Also, that the crossperi orations meet the upright perforations at substantiallyright angles and that the cross-perforations do not extend beyond the upright peri omtions thereby eliminating the detrimental feature of extending the cross-perforation onto the stubs which cannot be avoided in the double run and which is very unsatisfactory.

The invention is obviously not limited to the specific embodiment thereof herein illustrated and described, but is capable of many modifications and alterations within the spirit and scope of the invention as set out in the appended claims.
